Example VOEvents [public]

Note: There are actually two distinct VOEvent formats used to contain information about GW event candidates. GraceDB produces one format and makes it directly available through the GraceDB web page for the event, and also through a certain query syntax. GCN/TAN receives that format from GraceDB but translates it into a different format which follows the GCN/TAN schema.

GW alerts come in four types (each of which can be represented in either format): Preliminary, Initial, Update, and Retraction. See the VOEvent documentation for a detailed description of their meanings.
